Program Operations
mand requires two bus WRITE operations fewer than the standard WRITE TO BUFFER
PROGRAM command.
The UNLOCK BYPASS WRITE TO BUFFER PROGRAM command behaves the same way
as the WRITE TO BUFFER PROGRAM command: the operation cannot be aborted, and
a bus READ operation to the memory outputs the status register.
The WRITE TO BUFFER PROGRAM CONFIRM command is used to confirm an UN-
LOCK BYPASS WRITE TO BUFFER PROGRAM command and to program the n + 1
words/bytes loaded in the program buffer by this command.
WRITE TO BUFFER PROGRAM CONFIRM Command
The WRITE TO BUFFER PROGRAM CONFIRM (29h) command is used to confirm a
WRITE TO BUFFER PROGRAM command and to program the n + 1 words/bytes loaded
in the program buffer by this command.
BUFFERED PROGRAM ABORT AND RESET Command
A BUFFERED PROGRAM ABORT AND RESET (F0h) command must be issued to reset
the device to read mode when the BUFFER PROGRAM operation is aborted. The buffer
programming sequence can be aborted in the following ways:
? Load a value that is greater than the page buffer size during the number of locations
to program in the WRITE TO BUFFER PROGRAM command.
? Write to an address in a different block than the one specified during the WRITE BUF-
FER LOAD command.
? Write an address/data pair to a different write buffer page than the one selected by
the starting address during the program buffer data loading stage of the operation.
? Write data other than the CONFIRM command after the specified number of data
load cycles.
The abort condition is indicated by DQ1 = 1, DQ7 = DQ7# (for the last address location
loaded), DQ6 = toggle, and DQ5 = 0 (all of which are status register bits). A BUFFERED
PROGRAM ABORT and RESET command sequence must be written to reset the device
for the next operation.
Note: The full three-cycle BUFFERED PROGRAM ABORT and RESET command se-
quence is required when using buffer programming features in unlock bypass mode.
PROGRAM SUSPEND Command
The PROGRAM SUSPEND (B0h) command can be used to interrupt a program opera-
tion so that data can be read from any block. When the PROGRAM SUSPEND command
is issued during a program operation, the device suspends the operation within the pro-
gram suspend latency time and updates the status register bits.
After the program operation has been suspended, data can be read from any address.
However, data is invalid when read from an address where a program operation has
been suspended.
The PROGRAM SUSPEND command may also be issued during a PROGRAM operation
while an erase is suspended. In this case, data may be read from any address not in
erase suspend or program suspend mode. To read from the extended memory block
area (one-time programmable area), the ENTER/EXIT EXTENDED MEMORY BLOCK
command sequences must be issued.
